Terrarium and related method of use

ABSTRACT

A terrarium including a base, a support column, a top, and one or more panels with a closure is provided. The base can include a base channel, and the top can include a top channel. The top can be supported by the support column above the base. A panel can extend between the top and the base, being disposed in the top channel and the base channel, and forming an opening. Another panel can form a closure over the opening, with that panel optionally slidable to selectively access an internal compartment of the terrarium. A floater projection can be included on the closure panel and can engage a support rim on the base channel so as to support the panel and reduce friction of the panel moving relative to the base channel, for example, by supporting the panel above a channel bottom wall. Related methods of use are provided.

BACKGROUND OF THE INVENTION

The present invention relates to enclosures, and more particularly to aterrarium for housing plants and/or animals, and a related method ofuse.

There are a variety of terrariums used to house and keep animals, suchas reptiles, amphibians and fish, as well as other animals, and plants.Conventional terrariums are constructed to include transparent glass sothat users can observe the animals or plants from outside the terrarium.Many terrariums are constructed in the form of a box or rectangularshape for simplicity. For example, some are formed from four glass wallsarranged perpendicular to one another to form a box shape. The walls arefastened to a bottom and a rectangular cover rests atop the walls toprevent the animals from escaping. The cover typically is fullysupported by the walls, and is removable to access the interior of theterrarium for routine maintenance and cleaning. This can be helpful, butin many cases, access to the interior from the top of the terrarium canbe limited, particularly for tall-walled terrariums. Reaching to thebottom of the terrarium, where most animal waste is disposed, can alsobe burdensome, requiring awkward user orientation and/or special tools.

Many terrariums are used to house animals that require certain humidity,ventilation and thermal conditions. While some manufacturers try toaddress these requirements, adding special fans and/or humidifiers, theyusually fall short due to the size and shape of conventional enclosures.Frequently, the add-ons also increase electricity consumption, and thusthe cost of maintaining the terrarium.

Manufacturers typically ship terrariums in their final form. Where theterrariums are large, the shipping can be expensive, and the packagingfor the same can be overly bulky and unwieldy.

Conventional terrariums also can be outfitted with a variety ofaccessories, depending on the animals, plants and their native habitat.For example, some terrariums can have lights disposed in the cover. Topower these lights, an electrical cord extends from the cover and down aside wall of the terrarium. Frequently, the electrical cord is leftunconcealed, which can be unsightly and can present safety issues. Asanother example, a water dish can be placed on the floor of theterrarium for the animals to drink and use. While this can be helpful,some animals, such as snakes, prefer elevated positions in theterrarium, and are less likely to visit the water on the bottom. As yetanother example, artificial foliage or trees can be placed inside theterrarium for animals to use. These items, however, can be unwieldy anddifficult to secure, particularly where they are self-supporting orleaned into the corners of the walls.

Accordingly, there remains room for improvement in the field ofterrariums to provide easier access to the interior, less clutter foraccessories, better ventilation, easy shipping, and efficient use ofspace.

SUMMARY OF THE INVENTION

A terrarium including a base, a support column, a top, and one or morearcuate panels with a closure is provided.

In one embodiment, the base can include one or more base channels, andthe top can include one or more top channels. The top can be supportedentirely by the support column at a first preselected distance from thebase.

In another embodiment, the arcuate panels can extend between the top andthe base, and can be disposed in the top channel and the base channel. Afirst panel can include first and second side edges, separated from oneanother optionally forming an opening between the top and the base.

In still another embodiment, a second arcuate panel can be disposed inanother top channel and another base channel. This second arcuate panelcan form a closure over the opening. The second arcuate panel can beslidably disposed in the other top and base channels to enable it to beslid over and away from the opening to expose an internal compartment ofthe terrarium.

In even another embodiment, the at least one of the first and secondarcuate panels is a transparent panel so that a user can view inside theterrarium to thereby observe plants and animals therein.

In yet another embodiment, the support column can define an interiorbore, extending from an upper end to a lower end, effectively forming achimney or ventilation conduit for the internal compartment. The bottomof the chimney can be open to an underside of the base to permit airflowunder the base and into the chimney.

In a further embodiment, the support column can include first air ventsin the lower end and second air vents in the upper end. These vents canbe selectively opened and closed to modulate ventilation and air flowthrough the chimney and thus the internal compartment.

In still a further embodiment, the interior bore can house an electricalcord and/or a conduit which extends upward within the interior boretoward the top. The top can include a light that projects radiation intothe internal compartment, and the electrical cord can be joined with thelight to power it. The electrical cord optionally can be joined with aheater or some other electrical device disposed in the internalcompartment. The conduit can be joined with a watering bucket, which canintermittently drip water into the internal compartment.

In yet a further embodiment, a support ring can be joined with thecolumn. The support ring can be configured to support variousaccessories within the terrarium. For example, the support ring can bejoined with a watering receptacle, a platform and/or a perch. Thesupport ring engages the column and supports the accessory at apreselected distance from the base, usually depending on the type ofanimal housed in the terrarium. A user can adjust the location of thesupport ring relative to the column and thereby adjust the preselecteddistance to fine tune it for a particular animal.

In even a further embodiment, one or more spacers can be used to engageand support the support rings. The spacers also can selectively spacethe support rings vertically along the support column so that air ventsand opening in the column are easily accessible.

In another embodiment, the terrarium can include a base, a top and asupport column extending upward from the base and engaging the top tosupport the top. The top can include a top channel and the base caninclude a base channel having an upper support rim. A panel can beslidable disposed in the top channel and base channel. A first floaterprojection can be joined with the panel and can slidably engage theupper support rim.

In still another embodiment, the first floater projection can supportthe panel relative to the base channel such that a first panel loweredge minimally engages a base channel bottom wall, and optionally isdisposed out of contact or engagement with the base channel bottom wall.This can enhance the sliding action of the panel relative to the basechannel.

In yet another embodiment, the first floater projection can be joinedwith the panel adjacent a panel first side edge, generally near a firstend of the panel. A second floater projection can be joined with thepanel adjacent a panel second side edge, generally near a second, distalend of the panel. The second floater projection can support the panelrelative to the base channel adjacent the second end such that the firstpanel lower edge minimally engages the base channel bottom wall, andoptionally is disposed out of contact or engagement with the basechannel bottom wall. This can further enhance the sliding action of thepanel relative to the base channel.

In even another embodiment, the first floater projection can be in theform of a handle such that a user can engage the handle and slide thefirst panel, relative to the base channel and the top channel, all whilethe handle supports the first panel lower edge above a channel bottomwall so that the panel slides effortlessly in the base channel.Optionally, the first floater projection can completely support thefirst panel above the channel bottom wall so that the first panel loweredge does not engage that channel bottom wall during operation of thefirst panel, and optionally is spaced a gap from that channel bottomwall.

In still even another embodiment, the first panel can be an arcuatepanel and can include a first floater projection that forms a handleoriented generally vertically at a first end of the first panel, as wellas a second floater projection at a second end of the first panel. Thefirst panel can form a closure over an opening. The first floater andsecond floater projections can engage a portion of a base channel andsupport a substantial portion of the weight of the first panel so that afirst panel lower edge floats above a channel bottom wall of the basechannel, reducing friction of that lower edge engaging the base channelso that the arcuate panel opens easily.

In still a further embodiment, a method of using the terrarium isprovided. The method can include: placing a base including a first basechannel, on a support surface; joining a support column with the base,the support column defining an interior bore that forms a chimneyadapted to convey air from adjacent the base upward; joining a top withthe support column, the top including a first top channel, the top beingsupported entirely by the support column at a first preselected distancefrom the base; moving a first flat, planar sheet in the first basechannel and in the first top channel so as to bend the first, flatplanar sheet into a first arcuate panel; forming an opening betweenfirst and second ends of the first arcuate panel; and forming a closureover the opening with a second arcuate panel.

The current embodiments of the terrarium and related methods of providebenefits in the field that previously have been unachievable. Forexample, where the support column supports entirely the top, noadditional structure is needed to support the top. Thus, the arcuatepanels can be slidable and movable relative to the top without alteringthe integrity of the terrarium. Where the support column forms achimney, that component provides ventilation that was not previouslyavailable. Where the chimney is associated with selectively modifiableair vents, a user can precisely modulate ventilation and heat in theinternal compartment. Where the modular support rings and accessoriesare included, a user can custom build their own terrarium based on theirpersonal preferences or those of the animals housed therein. In caseswhere the support column includes an interior bore, unsightly electricalcords and other conduits can be selectively concealed therein. Inaddition, where the arcuate panels are initially provided as flat planarsheets, those sheets, as well as the other components of the terrariumcan be shipped in a relatively flat, manageable configuration and inassociated packaging.

These and other objects, advantages, and features of the invention willbe more fully understood and appreciated by reference to the descriptionof the current embodiment and the drawings.

DESCRIPTION OF THE CURRENT EMBODIMENTS

A current embodiment of the terrarium is illustrated in FIGS. 1-21, andgenerally designated 10. The terrarium can include a base 20, a top 30and a support column 40. The support column can be configured to definean interior bore 43 that extends from a first or lower end 41 to asecond or upper and 42. The interior bore 43 can form a chimney withinthe confines of the terrarium. This chimney can provide ventilation andcan circulate air within the internal compartment 50 of the terrariumvia a system of one or more vents, for example lower and upper vents 41Vand 42V. The support column 40 also can be constructed so that itsubstantially entirely supports the top 30 relative to the base 20,holding the top a first preselected distance D1 therefrom. The supportcolumn can support optionally 95%-100% of the weight of the top 30,while the one or more arcuate panels 61 and 62 optionally can support5%-0% of the weight of the top 30.

The arcuate panels themselves can be constructed initially as flat,planar sheets of material. When the flat sheets are initially slid intorespective channels of the top and the base, the sheets bend and conformto an arcuate shape, thereby forming the arcuate panels 61 and 62. Thearcuate panels can be configured so that the first arcuate panel 61,after installation, remains substantially stationary relative to itschannel, as well as the top and the base. This first arcuate panel alsocan form an opening 99O between its left and right side edges 61L and61R, as shown in FIG. 1. The second arcuate panel 62 can form a closureover this opening as shown in FIGS. 2 and 22-24. Optionally, the secondarcuate panel 62 can slide relative to the top and base, generallyparallel to the first panel, to open and close the opening 90O.

As used herein, a terrarium can refer to a vivarium for animals and/orplants, optionally including at least one transparent panel so the samecan be viewed by a user. The terrarium herein can be used with any typeof amphibian or reptile, such as lizards, frogs, snakes, alligators,salamanders, newts and the like. The terrarium also can be used withaquatic animals, such as various types of fish and the like. Theterrarium can be used with land dwelling or tree dwelling animals, andcan be utilized with virtually any type of plant and/or foliage, aloneor used to form habitat for animals housed in the terrarium.

Further, as used herein, an arcuate panel can refer to any panel orsheet that is formed to include at least one rounded portion. Forexample, a panel can be pre-formed and/or partially bent to form apartial cylindrical shape, a partial elliptical shape, a partial ovalshape, a parabolic shape and the like when the panel is viewed from anupper or lower edge thereof. The at least one rounded portion can bejoined with other more linear or curvilinear portions, depending on theapplication.

The individual components and construction of the terrarium 10 will nowbe described in further detail. Referring to FIGS. 1 and 3-5, theterrarium 10 includes a base 20 and a top 30. The base 20 includes anouter periphery 20O. This outer periphery 20O as illustrated can be inthe form of a circle. Of course other shapes, such as polygons,trapezoids and other shapes can be used to form the outer perimeter. Thebase 20 includes an upper surface 20U and a lower surface 20L. The uppersurface 20U generally faces upward, toward the internal compartment 50.The lower surface 20L generally faces downward toward a support surfaceSS upon which the terrarium is placed. The lower surface 20L can includeone or more feet 20F. These feet can place the base 20 and in particularthe lower surface 20L a preselected distance F1 from the support surfaceSS. Accordingly, airflow AF can move toward the opening 25 of the base20, which can be directly associated with an in fluid communication withthe chimney and/or interior bore 43 of the support column 40.

The base 20 can define a base opening 25 in a central location relativeto the outer periphery 20O. Where the outer periphery 20O is circular inshape, the opening 25 can be disposed directly in the geometric centerof the outer periphery 20O. Of course, in other constructions, there canbe more than one opening 25 that is defined in the base for more thanone support columns, and these openings can be displaced from thegeometric center of the outer periphery 20O. Optionally, more than onesupport column can be utilized in the terrarium 10 and spaced accordingto the support function thereof. Further optionally, all the supportcolumns can be spaced inward from any outer walls or arcuate panels areselected distance, in some cases, so that the support columns do notengage or contact those walls or panels.

The opening 25 itself can include a threaded interior 25T. This threadedinterior 25T can mesh with corresponding threads on the lower end 41 ofthe support column 40. In this manner, the support column 40 can bethreaded into, and fastened or secured fixedly to the base 20.Optionally, the opening can be absent, and the support column can beintegrally formed with the base. In other constructions, the supportcolumn can be fastened and/or secured to the base using clamps or thelike. Further optionally, the support column can be joined fixedly withthe top and/or the base using other connections. For example, the columncan be adhered, welded, melted to, molded to, integrally formed with,pinned, locked or otherwise connected to the top and the base.

The base 20 can include a first base channel 21 and a second basechannel 22. Each of these base channels can respectively guide the firstarcuate panel 61 and the second arcuate panel 62. The first base channel21 can be disposed inwardly from the second base channel 22, andoptionally located a distance farther away from the outer periphery 20O.As illustrated, the channels can be of a circular configuration but ofcourse, if other panel shapes are desired, that shape can be modified toan oval, elliptical, partial parabolic or some other arcuate shape asdescribed herein.

Optionally, the first and second channels 21 and 22 can be U-shapedgrooves defined in the upper surface 20U of the base 20. In other cases,these channels can be U-shaped frames that extend upward from the uppersurface 20U. In some cases, a separate U-shaped channel hoop can bejoined with the base 20 to provide the channel. In other cases, therespective channels can be of an L-shape, with the lower portion of theL secured to the upper surface 20U of the basin 20. A variety of otherchannel configurations can be provided to guide the respective arcuatepanels 61 and 62, and to open and close the terrarium.

Optionally, as shown in FIG. 3, one or more of the first and secondchannels can be aligned with and in communication with an introducerchannel 23. This introducer channel can extend inward from the outerperiphery 20O to each of the respective channels. In this manner, asheet of material, for example a flat, planar sheet can be slid throughthe introducer channel 23 and selectively introduced into either therespective first and second base channels 21 and 22 as further describedbelow. Further optionally, the top 30 can include a similar introducerchannel.

Further optionally, as shown in FIG. 12, the base 20 can include abarrier wall 23B. This barrier wall can be used to form a barrierbetween the upper surface 20U, upon which bedding B is placed, and thebase channels 21, 22. This barrier wall 23B can prevent the bedding Bfrom entering the base channels 21 and 22, which in turn can preventthat bedding from impairing movement of the arcuate panels within thosechannels. The barrier wall can be of a variety of heights, for exampleoptionally 2 inches, further optionally 1 inch, even further optionally½ inch or smaller, or larger, depending on the bedding, location of thechannels and activity of the animals in the bedding B. Alternatively,the barrier wall can be deleted from the construction and the uppersurface 20U can include a recess defined in the base 20 so that thebedding is disposed below the first and second channels 21 and 22. Otherconstructions are contemplated for maintaining the bedding out of thechannels.

With reference to FIG. 3, the top 30 can be of a similar shape inconfiguration as the base 20. The top 30 can include an outer periphery30O that is similar and/or identical to the periphery of the base 20O.The top 30 also can define first and second top channels 31 and 32.These channels can be constructed similar to the base channels 21 and22, and when the support column is joined with both the top and thebase, the top channels 31 and 32 can be generally parallel with thefirst and second base channels 21 and 22, with each generallyequidistant from the center or longitudinal axis LA of the terrarium. Ofcourse, where other shapes are used for the base and top, these channelscan vary in distance from that longitudinal axis LA.

As shown in FIG. 2A, the panels 61 and 62 firs within the first andsecond top channels 31 and 32 so that a gap G is established between theupper edge 62U of the second panel 62 and the base or bottom 32B of thesecond channel 32. This gap can be approximately optionally 1/32 inchesto ¾ inches, further optionally 1/16 inches to ¼ inches, or otherdistances depending on the application and the configuration of thechannels and panels. A similar gap G likewise can be established betweenthe upper surface 61U of the first panel 61 and the bottom 31B of thefirst top channel 31. Optionally, this gap G can exist between thepanels and the channels, or more generally a space can exist between thepanels and the top, because the support column 40 supports virtually allof the weight of the top 30. Thus, the panels 61 and 62 may not supportany of the weight of the top 30. In this manner, the upper edges ofthese panels are simply disposed in the respective channels, withoutbearing much if any weight of the top 30.

As further illustrated in FIG. 2A, each of the first 61 and second 62arcuate panels, when installed fully in the respective top channels (aswell as the base channels, although not shown) can exert an outwardforce F1, F2 against the outside walls 32O and 31O of the respective topchannels 32 and 31. These forces can be generated if the panels 61 and62 initially are installed in the terrarium as flat, planar sheets ofpolymeric material. Optionally, the forces and engagement by the arcuatepanels can be substantially only on the outside walls 32O and 31O of thechannels, but not the inside walls 32I and 31I of the channels. In somecases, the panels in the channels may only engage the outer walls, butnot the inner wells of the channels. As the sheets are bent uponinsertion into the channels, as described further below, the effect isthat the panels, when in the channels, exert the forces F1 and F2against the outer walls of the respective channels. This effect is dueto the panels trying to regain the former flat, planar sheetconfiguration. Indeed, the panels are urged outward, toward the outerboundaries of the channels, due to the flat, planar sheet memory of thepanels. If the outer walls were not present, radially outward from thelongitudinal axis LA relative to each of the respective first and secondchannels, then the arcuate panels 61 and 62 might spring outward, tryingto re-attain the flat, planar sheet configuration.

The top also can include a connector 35 that is configured to join withthe upper end 42 of the support column 40. As shown in FIGS. 3 and 5,the upper and of the support column can be threaded. The connectorelement 35 also can be correspondingly threaded. In this manner, the top30 can be threaded onto and fixedly joined with the support column 40.If desired, as shown in FIG. 11, the support column and connector 35 canbe joined via a locking pin 35L that extends through corresponding holesin the connector 35 and the upper end of the support column 40. This canprevent the top from rotating when the arcuate panels are installedrelative to the top, sliding within the top channels 31 and 32.

Optionally, where the terrarium is set up to include one or morelighting and/or heater systems, the top can define one or moreadditional openings 36. These openings 36 can extend completely throughthe top, for example, from the upper surface 30U to the lower surface30L of the top 30. These openings 36 also can be outfitted with a coverscreen 30 6S, which can be designed to ensure that the animals withinthe terrarium do not engage the light and/or heating element, whichcould potentially cause injury.

The base and top can be constructed from a variety of materials. Forexample these components can be constructed from plastic, wood,composites, metal and the like. The components can be formed viainjection molding, 3-D printing, pour molding, casting, machining andother similar techniques.

As shown in FIG. 5, the terrarium 10 also includes the support column40, which is secured to the base 30 and projects upwardly therefrom. Thesupport column can be in the form of cylindrical, hollow tubeconstructed from a relatively high-strength material so that it cansupport the weight of the top 30. As mentioned above, the support columncan define an interior bore 43. The support column can include uniformsidewall 40SW that extends around the interior bore as shown in FIG. 6.Although not shown, in some cases, the support column can be a solidstructure, without an interior bore 43.

The support column can be tubular, defining the interior bore 43 fromthe lower and 41 all the way to the upper end 42 so that air can freelyflow through that interior bore. In some cases, the support column canbe constructed from a polymeric pipe and/or a steel pipe or metal pipe.

As shown in FIGS. 5 and 6, the support column can be outfitted toinclude multiple access ports 40AP. These access ports can be sized toextend an optional electrical cord there through to power a electricaldevice at a predetermined location along the support column, and thus apreselected distance away from the base 20. Of course, the supportcolumn can be used to introduce water, gases or other items into theinternal compartment depending on the application.

As shown in FIG. 6-7, the support column 40 can define first or lowerair vents 44 adjacent the lower end 41. These air vents can beconfigured to draw in or expel air from or into the support column. Inthis manner, airflow can move through the interior bore 43, optionallyimproving ventilation and air circulation within the internalcompartment 50. The air vents 44 can be opened and closed by use a firstventilation unit 45 which can be slid in direction S over the supportcolumn 40 and into communication with the first air vents 44.Optionally, the first ventilation unit 45 can include correspondingvents 45 of the can be selectively aligned or misaligned with the firstair vents 44, thereby opening and closing those vents 44. In thismanner, a user can modulate airflow into the chimney/support column, andthus the respective ventilation in the internal compartment 50. Thefirst ventilation unit 45 can be rotatable in direction R to selectivelyaligned and misalign the vents 45V with the first vents 44, therebyaltering airflow through both. If desired, the ventilation unit 45 canbe outfitted with ventilation screens 45S disposed in the vents 45V toprevent animals from escaping from the internal compartment 50 throughthe vents 44.

As shown in FIGS. 9 and 11, the support column 40 can further define asecond air vents 44′ adjacent the upper and 42 of the support column 40.These air vents can be selectively opened and closed via the secondventilation unit 45′ which is configured similar to the firstventilation unit 45, and operates in a manner similar to that describedabove in connection with that unit 45. Further optionally, the first andsecond air vents 44, 44′, and associated ventilation units 45, 45′, cancooperate to provide selective fluid communication within the supportcolumn and the internal compartment 50. As an example, the air vents 44in the lower and can operate as a cold air return to expel cold air fromthe bottom of the internal compartment 50. The upper vents 44′ can beused to expel warm air from the chimney into the internal compartment50, or alternatively these air vents in the upper end 42 can be used tovent excess heat within the internal compartment out through the vents44′, into the support column. As will be evident, the upper and lowervents can function in a manner so that the support column, and inparticular the interior bore 43 acts as a chimney. As shown in FIG. 6,airflow can go into the lower vents 44. As shown in FIG. 11, airflow cantravel through the chimney and out the vents near the upper end 42 ofthe support column. As shown in FIG. 13, airflow can optionally flow outthrough the top vent 32V defined by the top 30 of the terrarium 10.

Referring to FIGS. 7-10, the support column can be configured toaccommodate a variety of spacers 46P and support rings 46S. The spacers46P can be used to selectively space the support rings 46S from the base20. The spacers optionally can be of a preselected height to ensure thatthe support rings 46S do not obstruct access ports 40AP. The spacers cangenerally be of a tubular construction having an inner diameter that islarger than the outer diameter of the support column so that thespacers, as shown in FIG. 7, can be slid downward in direction S, tostack upon an engage the next lower component in the support column.

The support rings 46S can include in and interior diameter 46SI thatalso is slightly larger than the exterior outer diameter of the supportcolumn 40 so that the support rings can be slid down onto the supportcolumn. Optionally, the lower surface of the support ring 46S can engagean upper surface or other portion of the spacer to further support thesupport ring. The support rings 46S can be configured to support anaccessory, such as a platform 46B a water receptacle 46W, a perch 46C orother devices for the general entertainment, feeding and/or support ofanimals disposed and the housed in the internal compartment 50. Theserespective accessories can extend radially outward from the longitudinalaxis LA of the support column and/or terrarium. As shown in FIG. 10,multiple spacers 46P and multiple support rings 46S can be selectivelydisposed and supported by support column 40.

Although not shown, the support column 40 can be outfitted with avariety of additional ports and/or holes that extend between theinterior bore and the internal compartment 50 of the terrarium. Thesupport column can include heater elements, radiation units, lightingunits, watering units or other devices housed in or at least partiallyextending through these ports to provide heat, radiation, light and/orwater into the internal compartment 50.

As shown in FIG. 13, the support column 40, and in particular theinterior bore 43 within the support column 40, can be used to houseelectrical cords, conduits or other items. If desired, the terrarium canbe outfitted with a light unit 70, which optionally can be disposed inone of the openings 36 of the top 30. In this manner, as shown in FIG.14, the light 70 can emit light L downward into the internal compartment50. Of course, the light unit 70 can be replaced with a heater, a fan,or some other electrical device which can alter the environment withinthe internal compartment 50 to benefit of animals and/or plants housedtherein. As shown in FIG. 13, the light is joined with the electricalcord 72 which extends downwardly into the interior bore 43 the supportcolumn 40. The cord can extend out from the opening 25 in the base 20and outward beyond the outer periphery 20O of the basin 20. From there,the cord can be plugged into a power source.

In an alternative embodiment of the terrarium 110 shown in FIG. 26-28,the support column 140 and in particular its interior bore 143 can housecords for electrical devices in locations below the upper end 142 of thecolumn. For example as shown in FIG. 26, the support column can define alower access port 140AP. A user can extend and electrical cord 172through that lower access port 140AP. The electrical cord can extendinto the interior bore 143 of the support column. The electrical cord172 can be joined with an electrical water pump 170. In this manner, thecord of the water pump can be concealed within the support column andnot overly visible. The cord also can be captured within a notch 146 andof a special spacer 146P that is slid over the exterior of the supportcolumn. This can further conceal the access port 140AP so that animalscannot escape through it and into the support column.

In the alternative embodiment of the terrarium 110, shown in FIG. 28,the interior bore 143 of the support column 140 also can be used toconceal at least a portion of a conduit 173. This conduit can be awatering tube for a drip feeder to slowly drip water into the internalcompartment of the finished terrarium. The conduit can extend through aportion of the interior bore 143 of the support column 140. The conduitalso can extend through an upper access port 140AP′, and further througha notch 146N′ defined by yet another spacer 146′. In this construction,the access port 140 AP' can also be covered to prevent animals fromescaping there through.

Returning to the embodiment of the terrarium 10 shown in FIGS. 14-25,that construction can include one or more arcuate panels 61 and 62.These arcuate panels 61 and 62 can be constructed from a variety ofmaterials, depending on the application and the desired properties ofthe panels. As illustrated, the panels 61 and 62 can be constructed froma transparent, polymeric material such as Plexi-glass™, Lexan™ or othermaterials, such as composite materials and/or metal materials,optionally with adequate openings to make the panel appear to betransparent or semi-transparent, or other materials optionally capableof being transparent or translucent, and in some cases flexible when ina sheet form. The panels 61 and 62 alternatively can be constructed froma translucent material and/or an opaque material. For example, as shownin the alternative embodiment in FIGS. 29-30, the first panel 161 isconstructed from a metal sheet, which optionally can be previouslyconstructed in a flat planar configuration. The metal sheet may includea plurality of apertures and/or perforations, so that the sheet actslike a screen to provide air flow through the internal compartment ofthe terrarium. Of course, other sheets, such as plastic sheets, opaqueor otherwise non-transmissive can be used in its place. Furtheroptionally, when the perforated sheets and panels are used, the ventsand ventilation units might be eliminated from the construction,depending on the application.

As shown in FIGS. 14 and 18, the first panel 61 can include an upperedge 61U and a lower edge 61L distal from one another. Generally theupper edge 61U is configured to slide within the first top channel 31and the first base channel 21 when installed in the terrarium. The topedge 61U and the lower edge 61L can be generally parallel with oneanother. The panel 61 also can include a first side edge 61S1 and asecond side edge 61S2 disposed on an opposite side of the panel 61.These edges can be generally parallel with one another. Optionally, eachof the edges can be housed or otherwise concealed within a channel orflange 63. This channel or flange can optionally be of a U-shape, andcan protect the respective side edges of the panel to prevent cracking,chipping or damage to the same. These channels also can be outfittedwith projections and/or handles (not shown) to assist in moving thepanel 61 through the respective channels 21 and 31.

As shown in FIG. 14, the first panel 61 can be initially provided in theform of a flat, planar sheet of material. When the flat planar sheet isinserted into and moved through the respective top and bottom channels,it attains and arcuate configuration as shown for example in FIGS.15-18. This arcuate configuration can be dictated via the configurationof the top and base channels as further described below.

As shown in FIG. 18, after the panel 61 is fully installed in therespective top and base channels 31 and 21, it is of an arcuate shape.The upper edge 61U of the panel is disposed in the top channel 31, asshown in FIG. 2A, and described above. The lower edge is disposed in thebase channel 21. The first side edge 61S1 and second side edge 61S2 areseparated from one another by a distance to effectively form an opening99O between these edges. This opening provides access to the internalcompartment 50 of the completed terrarium 10. This opening can extendoptionally at least 10%, further optionally at least 20%, even furtheroptionally at least 30%, yet further optionally, yet further optionallyat least 40%, and even further optionally at least 50%, around thecircumference or outside dimension of the base 20. The precise size ofthe opening can be dictated by desired access to the internalcompartment 50.

Optionally, the first panel 61 can be rotationally constrained in therespective top and base channels. For example, as shown in FIGS. 16 and17, a first dowel 61D can be disposed in the base 20, and can projectinto the first base channel 21, thereby forming a stop against which theside edge 61S2 is disposed. A second dowel 61F can be placed in thefirst base channel 21 at another location, thereby forming a second stopagainst which the side edge 61S2 is disposed. These respective stops caneffectively form the size of the opening 99O. The stops also can preventthe first panel 61 from rotating and are moving when the second arcuatepanel 62 is opened and/or closed or otherwise moved in its respectivesecond top and base channels.

As shown in FIGS. 2 and 23, the second panel 62 also can be an arcuatepanel. It can be constructed from materials similar to those describedabove, and can be formed in the arcuate shape in a manner similar tothat described in connection with the first panel. The second panel 62can include an upper edge 62U, a lower edge 62L, and first and secondside edges 62S1 and 62S2. The distance between the first side edge 62S1and the second side edge 62S2 can be greater than or less than thedistance between the respective side edges 61S1 and 61S2 of the firstarcuate panel. Optionally, one or more additional arcuate panels can beadded to those as illustrated.

As with the first panel above, the respective side edges 62S1 and 62S2can be outfitted with channels to protect the edges. These channels canbe outfitted with a handle 62H (FIG. 19) the can assist in opening andclosing or otherwise moving the second arcuate panel 62. The secondarcuate panel is disposed in the respective top and base channels and isslidable at the front of the terrarium 10.

When fully installed, as shown in FIGS. 2, 23, and 22 the second arcuatepanel 62 spans between the edges 61S1 and 61S2 so as to substantiallyclose the opening 99O, and thus provide a complete enclosure of theinternal compartment 50. Optionally, a stop or dowel 62D, shown in FIGS.16 and 20, can be installed in the second base channel 22 so as to forma stop against which the side edge 62S1 of the second arcuate panel 62can stop, to thereby provide adequate closure of the opening 99O.Further optionally, to lock the terrarium in a closed configuration soanimals therein cannot escape through the opening 990, the secondarcuate panel 62 can be pushed against the stop 62D, which engages afirst side edge of that panel. In addition, a key or secondary removablepin 62F can be installed in the base 20 and project into the second basechannel 22. This in turn, forms another stop against which the secondarcuate panel 62 abuts. In this manner, the second arcuate panel 62 isheld in a fixed or locked configuration relative to the first arcuatepanel, as well as the base.

Optionally, although not shown, the second arcuate panel 62 can be of afixed arcuate shape. Rather than starting out as a flat planar sheet, itcan be molded or formed into an arcuate panel. This arcuate panel can bemovably joined with the terrarium, for example, directly to the sideedge of the first panel 61. This connection can be in the form of ahinge so that the second arcuate panel 62 can swing outward, therebyproviding access to the opening 99O. Further optionally, the arcuatepanels herein can be comprised of multiple narrow flat panels that arehinged together so that they can be installed in the respective top andbase channels.

A method of using the terrarium 10 will now be described with referenceto FIGS. 1-23. It will be appreciated that when the terrarium is used inconjunction with panels that are in initially in a flat, planarconfiguration, the entire terrarium and its components can be shipped ina relatively flat configuration. Depending on the size of the terrarium,the overall height of packaging for the terrarium, when shipped flat,can be optionally less than 1 foot, further optionally less than 6inches, and even further optionally less than 4 inches in height. Thelength and width, of course can vary depending on the sizes of the base,top and the panels, as well as the length of the support column. Withthe capability to flat ship the terrarium, associated shipping andhandling fees can be significantly reduced. Further, because the overalldimensions of the terrarium in the shipped state are significantly lessthan the overall dimensions of the terrarium in the fully assembledstate, the terrarium can be stocked in inventory without taking upsignificant retail floor space.

Turning now to FIGS. 3-11, the method of using the terrarium can beginwith the placing of a base 20 on a support surface SS. A support column40 can be installed relative to the base by screwing the lower end 41into the opening 25 of the base 20. With the support column installed,and optional locking pin (not shown) can be projected through thesupport column and a portion of the base so that the support column willnot rotate relative to the base. A variety of optional spacers, supportrings and ventilation units can be slid in direction S downward over thesupport column 40. The various support rings and their supportedaccessories can be oriented relative to the support column 40 in amanner desired by the user. When a sufficient number of spacers, supportrings and ventilation units are stacked on the support column as shownin FIG. 10, the top 30 can be threaded onto the upper end 42 of thesupport column as shown in FIG. 11. The top also can be rotationallylocked relative to the support column with a locking pin 35L. Ifdesired, as shown in FIG. 12, a barrier wall 23B can be installedadjacent the respective base channels 21 and 22.

Where the terrarium 10 includes a light 70, that light can be installedin the top 30, and in particular within an opening 36 to projectdownward from the top. Any respective electrical cords 72 can be snakedthrough the interior bore 43 of the support column 40 and plugged intothe appropriate power source. Any other electrical devices also can beinstalled at this point, and/or while the spacers and support ringsbeing installed on the support column. With the top 30 installed on thesupport column 40, that support column substantially entirely supportsthe top at the preselected distance D1 from the base 20. Optionally, noother structure is used support the top in this configuration.

With the top, base and support column constructed, the first and secondpanels 61 and 62 can be installed. As shown in FIG. 14, the first panel61 is provided in a flat, planar sheet configuration and is in the formof a transparent polymeric material. The first side edge 61S1 isinserted into the introducer channel 23, as shown in FIG. 15. That flatplanar sheet 61 is moved into the first base channel 21 and the firsttop channel 31. As the sheet moves further into the channel, it beginsto take on the curvature and art of those respective channels. In turn,the sheet 61 begins to bend and/or flex so as to take on an arcuateshape, thereby forming the arcuate panel 61. The first panel iscontinued to be moved until it is fully installed in the first basechannel and first top channel. The respective dowels can be placed tosecure the respective edges in desired locations. The side edges alsoform the opening 99O of the terrarium upon completion of installation ofthe first panel in the first top and first base channels.

The second panel 62 can be installed in a similar manner to that as thefirst channel 61. Again, the second channel can start out as a flat,planar sheet of material. It can be introduced into the second top andbase channels 22 and 32 via the introducer channel 23. It can bend andflex as it moves there through. Eventually, the second arcuate panel canbe placed over the opening 99O between the respective edges of the firstarcuate panel 61. In so doing, it effectively forms a closure over thatopening. Respective dowels and locking pins can be placed to secure thesecond arcuate flannel if desired.

After the terrarium 10 is assembled, the user can prepare it foroccupation by animals. Artificial foliage, watering receptacles, andother accessories can be placed within the internal compartment 50 foruse by the animals. Of course, optionally, the foregoing items can beinstalled before the panels if desired.

A second alternative embodiment of the terrarium is illustrated in FIG.31 and generally designated 210. This embodiment can be similar instructure, function and operation to the embodiments described herein.For example, the terrarium 210 can include a base 220 and a top (notshown) supported by the support column 240, as well as the first 261 andsecond 262 arcuate panels, which are disposed in respective top and basechannels, although not shown. The first arcuate panel 261 can also forman opening to 299O that spans across the base 220. This opening 299O canbe closed by a closure which is effectively formed by second arcuatepanel 262, as well as additional panels 267 and 268. The first andsecond arcuate panels can be fixedly disposed in their respective topand base channels. Indeed, the second arcuate panel 262 can berelatively immovable after installation relative to the first panel andor the base 220.

Optionally, the additional panels 267 and 268 can be hingedly, foldably,slidably, or otherwise attached to the first and/or second arcuatepanels, or some other support structure between the top and the base220. The panels 267 and 268 can be constructed from materials similar tothose from which the first and second arcuate panels are constructed.The panels optionally can be transparent, translucent and/or opaque. Thepanels can be perforated or vented to allow air to flow there through.The panels 267 and 268 can hinge, pivot and/or move inward or outward asshown in the direction of the arrows E. In this manner, the additionalpanels 267 and 268 provide access to the internal compartment 250 of theterrarium 210. Optionally, these additional panels can be of any number,and can be attached to the terrarium to form virtually any type ofclosure relative to the internal compartment 250.

A third alternative embodiment of the terrarium is illustrated in FIG.32 and generally designated 310. This embodiment can be similar instructure, function and operation to the embodiments described herein.For example, the terrarium 310 can include a base 320 and a top (notshown) supported by the support column 340, as well as a first 361arcuate panel, which is disposed in and can be fixed and immovablerelative to the respective top and base channels, although not shown.The first arcuate panel 361 optionally can be the only arcuate panelused in this construction. The first arcuate panel 361 can also form anopening to 399O that spans across a minor side of the base 320,generally only on one side of the support column 340. This opening 399Ocan be closed by a closure which is effectively formed by a singleadditional panel 362. This additional panel 362 can be hingedly,foldably, slidably or otherwise attached to the first arcuate panel 361,or some other support structure between the top and the base 320. Thepanel 362 can be constructed from materials similar to those from whichthe first arcuate panel is constructed. The panel optionally can betransparent, translucent and/or opaque, and can be perforated or ventedto allow air to flow there through. The second panel 362 can hinge,pivot and/or move inward or outward as shown in the direction of thearrows P. In this manner, the second panel 362 provides access to theinternal compartment 350 of the terrarium 310. Optionally, theadditional panel can be of any number, and can be attached to theterrarium to form virtually any type of closure relative to the internalcompartment 350.

A fourth alternative embodiment of the terrarium is illustrated in FIGS.33-34 and generally designated 410. This embodiment can be similar instructure, function and operation to the embodiments described herein.For example, the terrarium 410 can include a base 420 and a top 430, aswell as a first 461 arcuate panel, which is slidable in respective top431 and base 421 tracks associated with the top and base. The arcuatepanel 461 can be transparent. The terrarium also can include a secondarcuate panel 462. This arcuate panel can be generally fixed between thesupports 440A and 440B. Optionally, the panel 462 can be at leastpartially opaque and in the form of a metal mesh if desired.

The terrarium can include first and second support columns 440A and440B. As shown, these support columns can extend between the top and thebase and can fully support the top, rather than the arcuate panelsupporting the top. Indeed, the arcuate panels 461, 462 can be gapped attheir upper edges like the embodiments above. The support columns canfurther be in the form of hollow tubes so that electrical wires,conduits and/or plumbing 402 can extend upward and through the supportsto the internal compartment 450 and/or the top 430.

Generally, as shown in FIG. 34 each of the support columns can extend atleast partially within the internal compartment 450. One or both of thesupport columns 440A and 440B can be located inward relative to thefirst arcuate panel 461, as well as the outer base track 421 and toptrack 431, which both simply can be formed from short 1″-3″ tall wallsoutside the arcuate panel to hold the panel inward relative to it. Theseelements still, however, form respective top and base channels relativeto the top and base. One or both of the support columns can be of a “T”configuration having a capture portion 443 and a stop portion 444. Thecapture portion 443 can capture ends of the second arcuate panel 462,holding it in a fixed configuration relative to the supports. Anothercapture portion 445, opposite the portion 443 or the support, cancapture an end of an optional short base wall 447 adjacent the base. Asshown, the base wall 447 and base track 421 cooperatively form a channel421C relative to the base. Although not shown, a similar channel can beformed adjacent the top 430. The base 440B can include a stop portion444 that is placed immediately adjacent the track 421, and can form alimiting stop to arrest movement of the arcuate panel 461 in the track421 when the panel is closed as shown in FIG. 34. This can be helpfulwhen the arcuate panel 461 is closed with a handle 461H by engaging thehandle and/or the panel 461 against the stop portion 444.

The other support column 440A can be disposed inwardly from the track421 so that no part of the support column 440A stops movement of thearcuate panel 461, and thus the arcuate panel can slide past the supportcolumn 440A in a direction Y, generally following the track 421 outsideit, to form an opening between the support columns 440A and 440B wherethe arcuate panel once was located. This opening can be used access theinternal compartment 450. After access is no longer needed, the arcuatepanel 461 can be closed in direction Z until an end 461E engages thestop 444, thereby closing off the internal compartment 450.

A fifth alternative embodiment of the terrarium is illustrated in FIGS.35-38 and generally designated 510. This embodiment can be similar instructure, function and operation to the embodiments described herein.For example, the terrarium 510 can include a base 520 and a top 530, aswell as a first 561 closure panel, which is slidable in respective top531 and base 521 channels or tracks associated with the top and base.The first panel 561 can be opaque or transparent. Although shown asarcuate, this panel can be linear or flat when disposed in therespective channels. The terrarium also can include a second panel 562.This arcuate panel can be generally fixed between the supports 540A and540B, and can be divided into one or more parts, which can be opaque ortransparent as shown.

The terrarium can include first and second support columns 540A and540B. As shown, these support columns can extend between the top and thebase and can fully support the top, rather than the panels 561 and 562supporting the top. Indeed, the panels 561, 562 can be spaced to form agap between the top channel bottom wall and the upper edges of thesepanels, similar to the embodiments above. The support columns can bejoined at their upper ends with the top and at their lower ends with thebase. Generally, these support columns can support the top a preselecteddistance above the base like the embodiments above. The support columnscan support substantially all the weight of the top, such that the firstand second panels 561 and 562 do not support a substantial portion ofthat weight. In some applications, the support columns can be deleted(not shown), and the second panel 562 can support substantially all ofthe weight of the top. Optionally, this panel can be reinforced or of athicker dimension or stronger material than the first panel 561 in suchan application.

As shown in FIGS. 35 and 36 each of the support columns can extend atleast partially within the internal compartment 550. One or both of thesupport columns 540A and 540B can be located inward relative to thefirst panel 561, as well as the base channel 521 and top channel 531 asdescribed below. The support columns can be constructed from a tubularmaterial as shown in FIG. 37, and can include a slot or recess 540R thatreceives an end 562E of the second panel 562. This end 562E is shown asan immovable, generally fixed panel that extends between the firstsupport column 550A and the second support column 550B. The supportcolumns also can be fixedly secured with fasteners 530F to the top 530and/or the base 520.

As shown from a top view of FIG. 37, the base 520 and top 530 can begenerally in the form of an oval or other curved structures. Likewise,the respective first panel 561 and second panel 562 can be of thesecurved configurations. In some cases, each of the respective panels caninclude different radii of curvature. For example, the first panel 561can be arcuate, having a first curvature with a first radius R1 at afirst end 561E1 and a second curvature with a second radius R2 at amiddle portion 561M and yet another curvature with another radius R3 ata second distal end 561E2. Likewise, the respective base channel 521 andtop channel 531 and the respective walls thereof as described below canhave similar differing curvatures and radii. As also shown in FIG. 37,the panels 561 and 562 also can define the internal compartment 550along with the respective base and top.

As mentioned above, the top and base can define respective channels. Forexample, as shown in FIGS. 35, 37 and 38, the base 520 can include afirst base channel 521. This first base channel 521 can be in the formof a U-shaped track that extends upward from the base 520. This firstbase channel can include a first outer wall 521OW and an opposing firstinner wall 521IW. The channel can include a first channel bottom wall521BW. These different walls can be joined together as an integral pieceor can be several components that are fastened, secured or otherwisejoined with one another. The top channel 531 can be virtually identical,with a respective outer wall, inner wall and top channel bottom wallthere between. The top channel 531 however can generally face and opendownward, while the base channel generally faces and opens upward.

The base channel 521 can include a base support rim 522. The basesupport rim can be constructed from a low friction polymeric materialsuch as nylon, high-density polyethylene or a metal that is coated witha special low friction coating. This base support rim 522 can be in theform of a U-shaped strip that is placed over an upper edge 521OWE of theouter wall 521OW of the channel. The base support rim 522 can include anupper most surface 520U that is configured to directly engage thefloater projections 571, 572 as described below. The uppermost surface522U of the base support rim 522 can be of a rounded or curved, convexcross-section as shown in FIG. 35. With such a construction, the basesupport rim 522 only minimally engages the floater projections 571, 572as described below. Optionally, the uppermost surface 522U can be abeveled surface where two surfaces terminate at an edge or a point so asto reduce the amount of surface area of the base support rim thatengages the respective floater projections.

As shown in FIGS. 35, 37 and 38, the terrarium 510 includes the firstpanel 561 as mentioned above. This first panel 561 can be the firstarcuate closure panel that extends between the top and the base. Thefirst panel 561 can be slidably disposed in the first top channel 531and the first base channel 521, generally between the first base outerwall 521OW in the first base inner wall 521IW. The first panel caninclude a first upper edge 561U, a first lower edge 561L, a first end561A and a second end 561B. The first upper edge and first lower edgecan be distal from one another. A first side edge 561S1 can be disposedat the first end 561A of the panel, and a second side edge 561S2 can bedisposed at the second end 560B. Optionally, these edges can be coveredwith a protective U-shaped strip 561P. Optionally, these edges can beopen to the environment like the upper and lower edges of the panel.

The first lower edge 561L can be disposed in the base channel 521, whilethe first upper edge 561U can be disposed in the top channel 531. Asshown, the panel 561 is shown in arcuate form, having curvatures withmultiple radii of curvature R1, R2 and R3. It is to be noted that thispanel, as well as the second panel 562 can be installed in therespective top and base channels in a manner such that the panels arebent from a flat, generally planar shape to an arcuate shape as shown toachieve the respective arcuate, multi-curvature configuration to fit inthe respective base channel and top channel. As described in connectionwith the embodiments above, the interfitment of the first panel and thesecond panel in the respective portions of the base channel and/or topchannel forcibly maintains the arcuate or curved shape of those panels.These respective panels are urged outward to engage the respective outerwalls of the respective top and base channels, due to the panelsnaturally tending toward their original flat, planar shape as describedin connection with the embodiments above.

The first panel 561 can have an arcuate shape when viewed from the topview in FIG. 37. This first panel, however, is slidable in the bottomchannel 521 and the top channel 531. As the panel slides in thesechannels, different portions of the first panel 561 bend as they areguided by the respective base channel and top channel. For example, asthe panel 561 is moved in direction M shown in FIGS. 37 and 35, thepanel 561 and its components, for example, the edges 561U, 561L slidewithin the respective base channel 521 and top channel 531. As thisoccurs, the portions of the panel are moved through the channels whichare curved and disposed along different radii of curvature, for example,R1 and R2 and R3. Accordingly, because it is flexible, the panel 561,bends to convert between and attain these different curvatures as itmoves within the channels. As a further example, the portion of thepanel near the first and 561E1 is initially configured in FIG. 37 tohave a first curvature corresponding to a radius R1. As shown in FIGS.35 and 38, as the end or side edge 561S1 of the first panel 561 is movedaway from the second end or side edge 562E of the second panel 562, orgenerally away from the support column 540A, thereby exposing an opening599O which opens to the internal compartment 550, that portion adjacentthe end, for example as shown in FIG. 35, starts to bend to achieve asecond curvature R2. As that panel 561 continues to open and increasethe size of the opening 599O, the portion of the panel can achieve athird curvature associated with a third radii R3. The multiple portionsof the arcuate panel also likewise can achieve different curvatures asthe panel slides in the respective base channel and top channel. Ofcourse, where the channels are of different shapes than that shown inthe figures, the panels can achieve those other curvatures. Further,where the channels are substantially linear or straight, the panel canbend or straighten going into or out from that linear portion of thetrack. Optionally, the panel can transition from a first curvature to asecond curvature and so on. Further optionally, the panel can transitionfrom a first curvature to a linear configuration to a second curvatureor configuration, again depending on the shape of the respectivechannels within which the panel slides. Further optionally, the panelcan bend as it slides in the base channel and/or the top channel suchthat a portion of the panel transitions from a first curvedconfiguration to a second, different curved configuration in differentportions of the respective channels. Still further optionally, the panelcan bend as it slides in the base channel and/or the top channel suchthat a portion of the panel transitions from a first curvedconfiguration to a generally linear configuration in different portionsof the respective channels.

As mentioned above, with reference to FIGS. 35 and 38, one or morefloater projections 571 and 572 can be included in the terrarium 510 andjoined with the first panel 561 or generally a panel that moves orslides relative to the top and base or the top channel and bottomchannel. In general, the first floater projection 571 can be configuredto engage the base support rim 522 to support a substantial portion ofthe weight of the first panel 561 such that the first panel lower edge561L generally has low friction engagement with the bottom wall 521BW orgenerally with the base channel 521. In some cases, the engagement ofthe first floater projection 571 is such that its lower edge 561L floatsabove the first base channel bottom wall 521BW. Accordingly, frictionbetween the first panel and the base channel bottom wall issubstantially reduced. The first panel 561 can slide from a closedposition, shown in FIG. 37 to a more open position, for example, asshown in FIGS. 35 and 38. With this lowered friction, the first panel561 can be easier to move and slide, as it transitions and bendsoptionally through the respective base and top channels. In turn, thiscan facilitate opening of the first panel 561 to expose the opening 599Oand the internal compartment 550, and to access that internalcompartment through the opening.

As shown in FIG. 35, the first floater projection 571 can include afirst elongated flange 573 that extends generally between a base supportrim 522 associated with base channel 521, and a top rim 531R associatedwith the top channel 531. The top rim can be constructed similarly tothe base support rim 522 except oriented upside down. The first floaterprojection 571 can be disposed between the top rim and the base supportrim. Optionally, the first elongated flange 573 can form a first handlethat is graspable by a user. The first elongated flange can extendsubstantially vertically along the first panel side edge 561S1 at thefirst end 561A of the first panel 561. This flange 573 can extendbetween the first upper edge 561U and the first lower edge 560L.Optionally, the flange can be segmented into different upper and lowerportions. Further optionally, the elongated flange can be a singleprojection that extends adjacent the side edge 56151, above the loweredge 560L of the panel 561. In other cases, the first floater projection571 can be disposed distal from the respective end 561A of the firstpanel 561. For example, it can be disposed midway between the first andsecond ends of the panel, depending on the application.

As shown in FIG. 35, the first elongated flange 573 includes a firstlower flange end 574. This lower flange end 575 can engage or directlyengage the base support rim 522 in a sliding manner such that the flangein particular the first lower flange end 574, can slide along the basesupport rim 522, and in particular along the uppermost surface 522U asthe first panel 561 slides in the first base channel 521. With the firstlower flange end engaging the base support rim, the first floaterprojection can support the weight of the first panel 561 adjacent thatfirst end rim. Therefore, the lower edge 561L of the panel 561 can beout of engagement with the portion of the bottom wall 521BW adjacentthat first end and/or the first floater projection.

As shown in FIG. 35, the first lower edge 561L can be disposedoptionally a distance or gap G5 above the first channel bottom wall521BW. This distance or gap optionally can be at least 0.5 mm, at least1 mm, at least 1.5 mm, at least 2 mm, at least 5 mm, between 0.1 mm and10 mm, inclusive between 1 mm and 20 mm, inclusive, or between 2 mm and50 mm inclusive. With this gap or distance G5 between the lower edge andthe bottom wall, friction between these components can be substantiallyreduced or eliminated. Thus, the primary force against the panel 561 canbe generated simply between the panel's outer surface and the channelouter wall 521OW and/or the panel's inner surface and the channel innerwall 521IW.

As mentioned above, one or more additional floater projections can beincluded or joined with the panel 561 to further support or reducefriction in the base channel and/or top channel. For example, as shownin FIG. 36, a second floater projection 572 can be joined with the firstpanel 561 adjacent the second end 561B of the first panel 561. Thissecond floater 572 panel can be substantially similar to the firstfloater panel with the respective flange and flange lower end, or othertype of projection. This second floater projection 572 also can engagethe base support rim 522, distal from the location where the firstfloater projection 571 engages the base support rim. This second floaterprojection 572 can support the first panel 561 relative to the firstbase channel 521, such that a first lower edge 561L of the first panel561 is out of engagement with the first base channel bottom wall 521BWadjacent the second end 561B of the first panel 561. Optionally, wherethe first floater projection and the second floater projectioncooperatively hold the first lower edge 561L out of engagement with thefirst base channel bottom wall 521BW between those floater elements, thedistance or gap G5 can be established between that first lower edge andthe first bottom wall, between those elements. Further, the first panellower edge can be out of engagement with the first base channel bottomwall between the first end and the second end of the first panel withsuch support. Of course, other floater projections can be includedbetween the ends to position the first panel lower edge out ofengagement with the first base channel bottom wall or otherwiseestablish a gap or distance G5 between those elements.

As mentioned above, the first floater projection 571 can form a handleor graspable portion that can be manually grasped by a user adjacent thefirst end 561A of the panel 561. The user can slide the first floaterprojection 571 on or relative to the base support REM and thereby slidethe first panel relative to the first base channel 521 from a closedposition to an open position relative to an opening 599O. Intransitioning from the closed position, shown in FIG. 37, to an openposition, shown in FIG. 38, the opening 599O can enlarge to gain furtherexposure and access to the internal compartment 550. Is also to be notedthat the second floater projection 572, where included, also can form ahandle that can be used to slide the first panel 561 relative to thebase channel 521 and the top channel 531, and thereby open and/or closethe first panel relative to the opening 599O and/or the internalcompartment 550.

As shown in FIG. 36, the first panel upper edge 561U likewise can beslidably disposed in a top channel 531, which includes an inner wall andan outer wall, similar to the base channel described below. Asillustrated, the first panel upper edge 561U can be spaced a gap ordistance G6 from the first top channel bottom wall 531BW. This gap ordistance G6 can be similar to the gap G5 described above. The upper end575 of the floater projection 572 can engage the top rim 531R of the topchannel 531 to prevent or impair that first panel upper edge 561U fromengaging the bottom wall 531BW of the top channel. This, in turn, canreduce the amount of friction between the upper edge 561U and the bottomwall of the top channel 531BW. Optionally, the first and second floaterprojections are disposed movably and slidably between the top rim andthe base support rim. Further optionally, the first and second floaterprojections can guide the panel along the base support rim to reducefriction between the panel lower edge and a bottom wall of the channel.Again, this can reduce friction and facilitate opening of the panel orotherwise moving the panel relative to the respective channels.
